6个变态的C语言Hello World程序

下面的六个程序片段主要完成这些事情：

 

输出Hello, World

混乱C语言的源代码

下面的所有程序都可以在GCC下编译通过，只有最后一个需要动用C++的编译器g++才能编程通过。

 

hello1.c

 

    #define _________ }

    #define ________ putchar

    #define _______ main

    #define _(a) ________(a);

    #define ______ _______(){

    #define __ ______ _(0x48)_(0x65)_(0x6C)_(0x6C)

    #define ___ _(0x6F)_(0x2C)_(0x20)_(0x77)_(0x6F)

    #define ____ _(0x72)_(0x6C)_(0x64)_(0x21)

    #define _____ __ ___ ____ _________

    #include

    _____

 

hello2.c 

 

    #include
